My personal interest in Wolfram from the start is because of Wolfram's BIG KNOWLEDGE BASE. And also the way Wolfram could "filter" and "re-present" those data back to users in an interactive and rich kind of way. I supposed it would be a really good personal case study and research for DATA VISUALIZATION . If you are interested in Data Science, you should also check thing like R Programming. Or maybe look up some ways Python can process data. SomethingData[] Now, we know that Wolfram knows A LOT. However to access those knowledge, we need some kind of understanding about the way Wolfram store the data. We can tell Wolfram to QUERY data using Wolfram Language SYMBOL, which I believe it will give you ENTITY, and further more the PROPERTIES of ENTITY. For example: 1) Supposed we want to know more about our PLANET: Earth . Wolfram recognize this "Earth" as a String. What if we want to actually find out more about ENTITY called EARTH? 2) We cou...
